<label>Second Number</label>
<input type="number" name="second_num" /> <br />
<label>Third Number</label>
<input type="number" name="third_num" />
<input type="submit" name="" value="Submit" />
</form>
</body>
<?php
if($_POST){
$first_num = $_POST['first_num'];
$second_num = $_POST['second_num'];
$third_num = $_POST['third_num'];
$sum = $first_num + $second_num + $third_num;
echo 'Sum: '.$sum;
}
?>

<body>

<label>First Number</label>

<label>Second Number</label>

<label>Third Number</label>

</form>

</body>

<?php

if($_POST){

$first_num = $_POST['first_num'];

$second_num = $_POST['second_num'];

$third_num = $_POST['third_num'];

$sum = $first_num + $second_num + $third_num;

echo 'Sum: '.$sum;

}

12. Write a PHP program to display first and last character of a string.

<?php
if($_POST){
$string = trim($_POST['text']);
$length = strlen($string);
for($i = ($length - 1); $i >= 0; $i--){
if($i == ($length-1)){
echo 'Last character is: '.$string[$i];
}
if($i == 0){
echo '<br />First character is: '.$string[$i];

$first_array = array(2, 4, 6, 8, 10);
$second_array = array(3, 5, 7, 9, 11);
$result_array = array();
for($i = 0; $i < sizeof($first_array); $i++){
$result_array[$i] = $first_array[$i] + $second_array[$i];
}
echo "<pre>";
print_r($result_array);
echo 'Sum of two arrays is: '.array_sum($result_array);
?>

<?php

$first_array = array(2, 4, 6, 8, 10);

$second_array = array(3, 5, 7, 9, 11);

$result_array = array();

for($i = 0; $i < sizeof($first_array); $i++){

$result_array[$i] = $first_array[$i] + $second_array[$i];

}

echo "<pre>";

print_r($result_array);

echo 'Sum of two arrays is: '.array_sum($result_array);

15. Write a program in PHP to store “coding in PHP” in a file named “coding.txt” .

fclose($myfile);
echo 'Content written to the file';
?>

<?php

$text = 'coding in PHP';

$myfile = fopen('coding.txt', 'w') or die('Cannot open file');

fwrite($myfile, $text);
